To aZZ whom it may concern.-

Be it known that we, GEORGE CRoMrroN and HORACE \VYMAN, of Worcester, county of "Worcester, State of Massachusetts, have invented an Improvement in Weft-Stop Mech- Figure 1 represents a broken front elevation of a. suificient portion of a loom to illustrate the application of our improved weft -stop mechanism thereto. tical section part of the breast-beam and lay with our weft-stop mechanism added.

detail on the line x Fig. 2, looking at the front of the lay-beam. Figs. 5 and 6 are details, partially in section, the first-named being taken on the line in at, Fig. 3, showing'the feeler in two different positions; Fig. 7 a detail of finger d; Fig. 8, a detail of lever h. Fig. 9 is an enlarged partial front view of the bracket which holds the weft-feeler block or head; Fig. 10, asection of Fig. 9 on the dotted line 3 Fig. 11- is an enlarged view of a modification, showing a different manner of uniting the weft-feeler with its pivot; Fig. 12, a section of Fig. 11 on the dotted line y"; and Fig. 13, a detail showing parts of the breastbearn, guide-plate, and bracket.'

The loom-frame A, breast-beam o, lay B, shipper-lever m, handle 15, pivoted at a, rod 8, connecting said handle t with the shipperlever m, notched guide-plate r, the pivoted block e", pivot a, and spring 0, are substantially as in our United States Patent No. 265,659, dated October 10, 1882, so need not be herein further particularly-described.

The breast-beam v, at its inner side, and preferably near its center, has attached to it a guide-plate, a, upon which a bracket, a is adj ustably secured by bolts a, passing through slots in the bracket, the latter having a horibly held bybolt b the shoe b, and upon which Fig. 2 represents in ver-.

Fi 3 is a top view of Fig. 2. Fig. 4. is a sectional in turn is secured'by a bolt, Z1 the base-plate a, slotted at 32. The bracket a so held may be adjusted vertically. Its slotted foot permits the shoe 1) to be adjusted horizontally toward and from the lay when the bolt Z2 is loos ened, and the slot 32 in the base-plate a permits the latter to be adjusted laterally toward 7 the loom side when the bolt 1) is loose. The shoe 1) has inwardly-extended lugs 11" at its sides to receive the slotted portion of the baseplate, and has downwardly-projecting lugs I)" at its ends (see Fig. 2) to embrace the foot a of the. bracket a This shoe assists in steadying the parts; but it maybe omitted, in which case the base-plate will rest directly uponthe bracket f, the rear end, (P, of the finger, by

its contact with the under side of bracket f, (see Fig. 5,) determining the descent of the front end of finger d. w

The projections 2 3 are open at their sides, as shown in Figs. 2, 5, and 6, for the passage through them of the head 0 of the lever 0 it having an inclined face, 4, (clearly shown in Fig. 3,) against which strikes the end of the finger d, when the weft-thread is broken or fails to holdup the feeler c as the lay is moving over the first portions of its course on its way forward, to cause the reed (not shown) to beat up the weft at the fell of the cloth. The lay has connected with it the bracket f, which carriesthe pivot g for the feeler e, the latter being shown as composed of a forked wire, attached by a screw, 6, to ablock or hub, one

' part of which is extended toward the center of the lay, and has a pin, 9, which sustains the link 9*, that at its lower .end is joined by pin 7 with lifting-lever h, pivoted on a pin, 8, in an ear of the bracket f. This lever h has a projection, 12, which, as the lay is moved backward, rides along over the top of adjustable guidec, made as a lever or arm, pivoted at 14,

on an ear, or, of the plate 0. The said guide I n is slotted, as shown clearly at 15, Fig. 6, to receive through it a bolt, 20, screwed into a part of the plate 0, and has a lug, 16, at its rear side, and immediately below the said lug is an adjustable screw, n held in an ear, n, of plate a. \Vhen the bolt 20 is loosened, the guide may be raised or lowered by turning the screw Win the proper direction. The position of the upper right-hand end of the guide a (see Fig. 2) determines the extent of upward movement of the rear end of'lever h, and consequently the upward throw of the feeler e at the backward position of the lay, while the shuttle crosses it to deposit the weft or filling between the warp. Lever h has its rear end convexed, as at 21, (see Fig. 8,) in the arc of a circle described about its pivot S, and is provided with a notch, 22, and a toe, 23. The finger (1 next the lever h is provided with a concaved recess, 24, a notch, 25, shoulder 29, and a projection, 26. The conveXed end of lever h rests in the concaved recess 24 of the finger (Z, and during the upward motion of the lever h from the position shown in Fig. 5 the corner 30 comes in contact with the under side of the projection 26 of the finger (Z and lifts the latter until the corner 30 of the lever passes the point of the said projection, after which the lever holds the finger without movement. At the same time the concave surface 24 of the finger comes in contact with the convex sur face 21 of the lever h, and prevents the finger d from rising beyondthe position imparted to it by the corner 30 of the lever h acting against the projection 26 of the finger, notwithstanding the lever continues to rise to the position to which the guide a will carry it. The finger d will remain at rest with its point just above the level of the top of the end 0 of the dagger-lever c and the said lever h, while the weft-feeler is held by the weft in the plane of the dotted line in Fig. 5, prevents the finger d from descending low enough to turn. the lever c as the lay 21 is moved forward. Should theweft be absent, the feeler e, unsupported by it,will drop below the position of the dotted line 28, Fig. 5, and the corner 30 of the curved end of the lever h will drop below the projection 26,which permits the finger (Z to drop by reason of its weight but to positively insure the descent of the finger d in the proper time, we have provided the lever h with the toe 23, which strikes the shoulder 29 of the finger d and throws it down quickly, so that the latter, as the lay is moved forward, will strike the inclined face 4 of the head 0 of lever of, and cause the said lever to be turned about its fulcrum, the stud 0", and stop the loom. As the portion 12 of the lever h during the backward movement of the lay travels upalongthe top of the guide a, the corner 30 of the said lever,striking the toe 26 of the finger, will lift the latter 5 but by the time that the end of the finger has been sufficiently elevated to be above the end 0 of the le- -finger, will hold it at rest.

ver'c the toe 26 thereof rests on the curved surface of the lever h, after which further elevation of the lever h, instead of lifting the The recess 22 allows traveling space for the projection or toe 26.

The shoulder 29 referred to may be omitted; yet it is desirable to retain it to insure positive downward movement of the finger d. The lever 0 at its front end, has an arm, 19, connected with it by bolt 19, which arm, when the shipper-lever m is locked in the notch of its usual holding-plate r, rests against the adjustable lug p on the rod 8, and consequently when the lever c is vibrated by the action of the finger d against its head 0 the arm 1), by its pressure against the block 19 of the rod 8, turns the piece 6 as described in the patent hereinbefore mentioned, and forces the shipper-lever m out of its holding-notch. The shipper-lever, when released from the notch of plate 1", will through other levers, as described in the, said patent, operate to shift the driving-belt and stop the loom.

The block or hub (shown best in Figs. 9 and 10) is of sufficient diameter to have made in it suitable holes for the reception of the feeler-wires, and that part of the feelerat the side of the said block nearest the breast-beam is bent at right angles against the block, as shown, thus forming a loop or eye, asshown in Fig. 9, through which and into a threaded hole in the block is inserted the screw 6, which connects the feeler c with the said block. The warp threads in line with the feeler rest upon the upper rounded side of the block or hub 9 or upon a shield, 40, at tached thereto, thus forming a smooth unobstructed surface for contact with the warp: threads as the lay is being reciprocated. This shield (shown in Fig. 10, it being omitted from all the Figs. 1 to 9, inclusive, to avoid confusion) shields the head of the screw 6, so that the warp-threads cannot catch it.

In Figs. 11 and 12 we have secured the con- 1 1o nected end of the feeler upon the upper side of the block or hub and in such modification the shield for the screw is attached to the side of the hub nearest the breast-beam, and the shield projects backward instead of forward, as in Fig. 10.
